CULTIVATOR.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed April 16, 1912. Serial No. 691,133.

To all 207mm it may concern Be it known that we, PEARL. A. Lewis and HENRY N. FAAS, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements 1n Cultivators, of which the following is a specification.

This invention relates to improvements in cultivators and more particularly to improvements on the machine illustrated in Letters Patent of the United States No. 961,762, issued June 21st, 1910, to H. E. Dodson and Henry N. Faas.-

One of the objects of the invention is to provide means for so connecting the respective gangs of cultivating disks to their supports that each gang may be quickly and readily moved from one of its operative positions to the other without the necessity of removing any parts or disconnecting the parts in any particular; it being understood that one of the operative positions of the disks is that in which they throw the earth away from the plants, while the other operative position is for causing the disks to hill toward the plants.

A further object is to simplify the construction and modepf operation of machines of the character referred to.

In the accompanying drawings,-Figure 1 is a sectional view through a portion of the support for one of the disk gangs showing the manner of adjust-ably securing the parts thereof together. Figs. 2 and 3 are details of the same. Fig. 41 is a rear view of a portion of the machine showing the gang of disks in one position of operation. Fig. 5 is also a rear view showing the disks in a different Position of operation.

Like parts are represented by similar characters of reference in the several views.

In the said drawings, 1 represents the rear rail of the frame of the machine, which, together with the brackets 2 connected at the respective ends thereof, forms an archshaped axle-frame. The ground-wheels 3 are pivotally connected to this arch-shaped frame, each of the axles 1 having an up turned portion 1 journaled in perforated ears or lugs 5 projecting laterally from the bracket 2.

The cultivating members are in the nathe parts.

ture of two gangs of disks arranged on opposite sides of the machine. The disks 8 of each gang are secured to a shaft which 1s journaled in bearings at the lower end of 15 upon which said plate 13 rests. The bolt 12 extends through the boss 14 and also through the yoke 10 and has a washer 12 overlying the plate 13 so as to pivotally connect the two plates together. As in the former patent referred'to, the plate 13 has an upwardly extending serrated portion 16 secured to the serrated face of a bracket 1'7 through the medium of the rod 18, the lower bent end of which extends through perforations in the parts 16 and 17 and is screw-threaded to receive the nut 19 so as to clamp the parts firmly together. As in the former patent, the rod extends up through perforated guides 20 extending laterally from a supporting head 21, adjustably secured to the bar 1 by set-screws 21 this support 21 also having pivoted thereto the usual lifting and presser lever 22 connected to the bracket 17 by the rod 23, which rod carries the coil-spring 23 interposed between the collars thereon so that pressure may be applied to the cultivating disks in the usual way.

In the operation of cultivators employing disk cultivating members, it is necessary to be able to so position the disks that they will hill toward the plants or throw the earth away from the plants, depending upon the conditions. One of the features of this invention is to provide means whereby each gang of disks may be so connected with its support that it may be quickly and readily moved from either one of these positions of operation to the other without the necessity of removing or disconnecting any of To accomplish this, one of the bearing plates forming the connection between each gang of disks and its support,

such as the plate 11, is provided with two series of serrations or teeth, one series 25 being located 1n the rear edge of the rim 15 of said plate, and the other series 26 being located in the front edge of the rim 15 of said plate. Cooperating with these serrations is a dog or pawl 27 on the plate 13, this pawl being located between two ears 28 on said plate and pivotally connected with said ears by a cotter pin 29. A coilspring 30 located in a housing 31 project- 7 ing upwardly from said plate 13, normally tends to hold said pawl in engagement with any one of the series of serrations; said housing being formed with a recess 32 to accommodate the pawl 27 when in the dotted line position shown in Fig. 1, to permit its disengagement with said serrations. As a result of this construction, the gang of disks may be held either in the position shown in Fig. 4 to hill toward the plants, or may be turned to the position shown in Fig. 5 to throw the earth away from the plants by simply raising the dog, and, by having the series of serrations on both the front and rear edges of the plate, it will be seen that the gang of disks may also be adjusted to any desired angle With respect to the line of draft in either one of the aforesaid positions of operation.

Having thus described our invention, we claim In a cultivator, a. disk cultivating member comprising a yoke, a bearing plate secured to the upper end of said yoke, said plate having a centrally upwardly-extending projection and an outer upwardly-extending flange, a support, a plate connected with said support having a journal for said projection, means for pivotally connecting said plates together, a series of notches arranged in the front and rear of said flange respectively, and a springpressed dog carried by said support plate for engagement with said notches to hold said cultivating member in different. positions of adjustment with respect to said support in both positions of operation of said cultivating member.

In testimony whereof, we have hereunto set our hands this 27th day of March 1912.
